Thats fair, but I was still more surprised when Wiggins all of a sudden could climb after being absolutely horrendous in mountains pre 2008. I will give you Thomas' Tour-win was more ridiculous than Wiggo's since Wiggo obviously was limited in the mountains and all in all 2012 was a Tour were everything aligned perfectly for him. Absolutely perfectly, and no one was really surprised since he got handed that victory on a silver platter with a absolutely dominating team, best imaginable route, infinite MIAS (most notably Contador), Schlecks and Evans sudden steep declines, Froome not being THAT Froome yet etc etc.Wiggins was ludicrous in 2009, sure, but at least you could wave things away slightly by accepting he never focused on the road (he rode it but was always a track specialist), and that it wasn't too far removed from an era when the GC guys were bigger, TT-focused machines than they tend to be nowadays, until the ridiculous transformation, whereas Thomas was a road rider all along, with a decade of us knowing what his skillset was, and then he changed it completely at 29. Yes, he was no mug uphill, winning the Bayern Rundfahrt on one of its only half-decent routes, but he was also never even remotely a 'climber' until 2015. Geraint Thomas' rider type pre-transformation was more like van Aert's than Wiggins making him a more viable comparison, and Geraint Thomas was like what happens if George Hincapie had actually gone on to lead Discovery Channel after Armstrong's retirement... and won the Tour de France.
Geraint Thomas IS George Hincapie, their trajectories and rider types are strikingly similar, only he didn't just win one ridiculous mountain stage, he won two ridiculous mountain stages back to back while looking physiologically like he'd eaten most of the climbers he was dropping. And then he won the Tour de France.
